I didn't expect that with this version as well... Previously the solution to this has been a clean instal, though this does require backing up your save before hand which you can find in your phones data directory.
yepp..
That worked...
But i see that you didn't set the "second saves directory" which i would recommend for modern android games as newer android versions don't let the user access the app-directories without having to root the phone...
(mine is fortunately rooted but most users aren't doing that for obvious reasons...)
You can find that variable there:
